HARROW AND PULVERIZER,

SPECIFICATION forming part of Letters Patent No. 389.985, dated September 25, 1888. Application filed lla3v 17, i888. rSerial No. 274,125. (No model.)

harrows and pulverizers; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter,and particularly pointed outin the claim.

In the accompanying drawings, Figure l is I5 a top plan view of a harrow and pnlverizer embodying ourimprovements. Fig. 2 is a longitudinal sectional view of the same, taken on the line a; x of Fig. l.

A representsareetangular frame, which comprises the side beams, B, the rear connectingbeams, C, and the parallel beams D, which counect the front ends of beams B.

E represents the driving-shaft, which is arranged transversely over the frame ata suitable distance from the rear end thereof, and is journaled in suitable bearings, H, o'n the upper side ofthe frame. To thc ends of the said shaft are Secured driving and supporting wheels I.

K represents an open cylindrical roller, which comprises a central shaft, L, a pair of circular heads, M, near thc ends of said shaft, a circular head or disk, N. arranged on the shaft midway between the heads M, and a series of spirally-arranged bars, which connect the said heads and are secured in peripheral recesses therein. Said spirally-arranged bars are provided with openingsP at suitable regular distances apart, and in the said openings are inserted the shanks of harrow or pulverizing teeth or hoes It, which may be either of the form here shown or of any other suitable shape. The shaft L of the cylindrical roller is journaled in bearings S near the front end of the frame, and near one end of the said shaft is secured a spur-wheel, T.

U represents an idle-wheel, which is journaled on a spindle, V, that projects inward from one of the side beams, E, and said idlewheel meshes with the wheel T.

The shaft E is provided near one end with a clutch-section, W.

vX represents a spur-wheel, which is feathered or splined on the shaft E, has a clutchsection formed on one side, at its hub, to ent gage the section l/V, and has its hub also provided with a peripheral annular groove, Z, which is engaged by the bifurcated front end ofan arm, A', the said arm having its rear end pivoted to the rear beam, C, of the frame. A spring, B', bears against one end of the hub'of wheel X, and is arranged on the shaft E, the function of the said spring being to normally keep the wheel X in engagement with the clutch on the shaft and to keep the said wheel also in engagement with the idlewheel U. .f

O' represents a hand-lever, which is pivoted on a spindle that projects forward Vfrom the rear beam of the frame. The said hand-lever is connected to the arm A by means of alink, D', and the said lever C' is further provided with a locking-bolt, E',which is adapted to engage a notched sector-plate, F', or other device with which the frame is provided, so as to secure the hand-lever at any desired position. Aseat, G', for the driver is mounted on a springarm, which is attached to thc rear beam of the frame.

I-I' represents the tongue, which has its rear end pivoted between ears or eyebolts I', that project from the front side of the frame.

K' represents a sector-plate,which is secured on the upper side of the parallel beams D, and

is provided with aseries of peripheral teeth or notches. Journaled in the said sector-plate is a rock-shaft, L', which has an arm, M', at one end connected. to a pair of ears, O', (which project upward from the rear end of the tongue,) by means of a link, P'.

R' represents a hand-lever, which is secured to the opposite end of the rock-shaft, and is provided with a locking bolt, S', which is adapted to engage the sector-plate, so as to seeure the said lever and the tongue at any desired elevation.

The operation of our invention is as follows: XVhen the wheel X is in engagement with the idle-wheel and the machine is being drawn across a plowed field, the rotation of the driving-shaft E is communicated to the cylinder K, thereby causing the latter to rotate in the same direction with the driving-shaft, and the teeth of said cylinder, by engaging the plowed IOO gronnd, serve to thoroughly stir and pulverize the same. By reason of the Wheel X. being larger than the wheel T on the pnlverizingcylinder, the latter is rotated at a higher rate of speed than the driving-shaft when the machine is in operation. When the machine is being drawn over the field and itis not desired that the same should be operated thereon, the handlever C is moved so as to cause the wheel to move inward on the driving-Shaft and become disengaged from the idle'wheel, and eonsequently the harrowingcylinder is rotated merely by contact with the ground.

Having thus described our invention7 we claim rlhe improved barrow and pulverif/,erllerein described and shown,eomprising thereetangular frame, the driving-shaft mounted in the rear portion of said frame, the driving-wheels on said Shafathe revolnble cylinder in the front eaees end of the frame, provided with radially-pro'- jecting teeth or hoes, gearwvheels between the driving-shaft and the shaft ofsaid cylinder, the hub of the rear gear-Wheels having an annular groove, the arm A', pivoted to the rear beam of the frame and having a bifurcated front end engaging the said groove, the spindle projecting forward f rom said rear beam of the frame, the lever fnlcrumed on said spindle, and the link D', connecting said lever to the arm A', substantially as specified.

VIn testimony that we claim the foregoing as our own We have hereto ai'iixed our signatures in presence of two witnesses.
